IMPROVEMENT IN RULING-HPENS.

The Schedule referred to in these Letters Patent and making part of the Same..

To all 'whom it may concern:

. is cut.

My 'improvement relates to that class of pens used by Stationers in ruling paper, and consists in making such pelis from a sheet of metal, having that portion, from which the points of the pens are to be cut, reduced to any desired degree of tenuity by the removal of the metal while in sheet, the object being to secure a pen with sufficient strength and stiffness, yet with a point as fine as may be required by the most delicate description of work, all as hereinafter more fully set forth.

The pensare cut tiom a sheet of brass, or other suitable metal, formed, as shown at D-in lig. 3, being very thin in the middle section, from which the points of the pens are cut, and thicker near the edges, in that part from which the body of the pens is formed.

The pens are cut ii'om the metal sheet D, point to point, and folded with their edges together, as shown in fig. 1.

The sheet, between the points or pens, is cut away, so as to form a square edge, and a narrow slit is cut at C C, between the pens.

-Ihe back is bent in the usual manner, to attach it to the frame in s uch manner as to give the proper angle to the peus.

This pen is distinguished from all others in this, that in the ordinary ruling-pens the backs are made double, by the application of a second thickness of metal for a portion of their length, for the purpose of support, the points only being left of a single thickness of the rolled sheet-metal.

The metal of which the points are made is of even thickness throughout, and the limit of the iineness of these common pens is xed by the thinness of the rolled metal to be found in the market.

y The doubleback, moreover, by capillary attraction, draws in inlcbetween the plates which compose it, and the rapid corrosion and destruction of the pen ensue.

In my improved pens, on the contrary, there being but a single thickness of metal employed, nosuch accumulation of ink can occur. The requisite strength is secured by using metal as thick as may be necessary to insure it, and any degree of ineness can be given to the points by the previous reduction of that portion of the sheet of metal from which they are cut.

'Ihe slits G form divisions between the pens, guiding the ink from the fountains towards 'the pens, and preventing its accumulation in drops.

What I clairn asl my invention, and desire-to secure by Letters Patent, is-

Machine-ruling-pens, made from'a sheet of metal having that portion, from which the points of the pens are out, previously reduced to any required degree of tenuity, by the removal of the redundant metal, while iu sheet, substantially in the manner described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing wit- Witnesses WILLIAM Roenes, Oms. J ELLIS.
